POTHOLE PROTECTION MECHANISM

摘要

A pothole protection mechanism provides additional support for the vehicle i n the event a wheel is driven into a hole while the platform is elevated. The mechanism includes an extendible and retractable pothole protection bar. A five-bar mechanism serves to actuate the pothole protection bar based on a position of the vehicle lifting section. The construction of the mechanism serves to prevent a crushing haza rd while deploying the bar and tolerates fixed objects on the ground while raising th e bar.
